5) Bistable/Monostable operation
The relays can be programmed to operate in bistable (on/off ) or monostable
(timed) modes (the period of activation can also be set in the latter case).
Bistable mode:
entering the value "0" sets the relay to activate when the code is fi rst entered,
then de-activate when it is next entered.
Monostable mode:
entering a value in the range 1 to 99 sets the relay to activate when the code is
entered and de-activate automatically once the specifi ed period of time (1 to 99
seconds) has expired.
Modifying relay timing
To modify the relay timing, fi rst cancel the relay code as explained in point 4 and
then enter another one.
Example:
if relay 1 was activated with code 55127 in bistable mode, proceed as follows to
change its mode to monostable:
1) Cancel the code by entering in sequence:
0 E start procedure
12345 E supercode
0 E cancel
55127 E code to be cancelled
2) Re-enter the code with the desired operating mode:
0 E start procedure
12345 E supercode
1 E identifi cation
5 E monostable mode, 5" delay
55127 new code
After this, relay 1 will activate on entry of code 55127 in monostable mode for 5".
6) Anti-coercion function
When the operator must be able to send an alarm without being noticed, the
anti-coercion function can be activated. The anti-coercion function, composed
of a single digit, must be entered after one of the relay codes, and activates not
only the relay in question, but also the timed anti-coercion output (5") (output
AL+).
Programming the anti-coercion function:
1) Enter "0" and "E" (start programming procedure code)
2) Check that the LED has lit up
3) Enter the supercode (see point 1), then "E"
4) Enter "4" (select anti -coercion function), then "E"
5) Enter the anti-coercion code (1 digit from 1 to 9), then "E"
6) The LED should now turn off
Example:
to set an anti-coercion code of 3, enter in sequence:
0 E start procedure
12345 E supercode
4 E anti-coercion function
3 E anti-coercion code
Now, when the relay code is followed by the anti- coer cion code, the output
relay as well as the anti-coercion output will both be activated (the latter timed
to 5" approx): 71032 3 E.
• The anti-coercion code MUST be entered after the relay code and before
the fi nal E.
• When the anti-coercion function is activated, the relay code may not be
more than 7 digits long.
• The anti-coercion output is between 12 Vdc and earth (max. 100 mA).
7) Programming the allowed errors number
This allows you to set the number of code entry errors allowed before the lock-
ing function is activated. If, for example, you set a value of 3, on the third incor-
rect code entry the key is locked for a period of 1 minute. You can also send an
alarm signal (output AL+), after the allowed number of errors, if this is provided
for during programming. To send the alarm, program "1" during the procedure,
otherwise program "0" (see below).
An incorrect code entry is the entry of a code not stored during programming,
followed by "E".
Programming the allowed errors number
1) Enter "0" and "E" (start programming procedure code)
2) Check that the LED has lit up
3) Enter the supercode (see point 1), then "E"
4) Enter the number "5" (error lock function) followed by "E".
5) Enter the allowed number of errors (1-9), but DO NOT enter "E".
6) Enter: "1" "E" to send an alarm when the key is locked; "0" "E" if you do not
wish to send an alarm.
7) The LED should now turn off
6
Example:
to program key locking after 3 errors without sending an alarm, enter in se-
quence:
0 E start procedure
12345 E supercode
5 E error function
3 number of allowed errors
0 E do not send alarm
8) Programming the relay 1 activation delay for a remote key input
This procedure sets the activation time for relay 1 on a remote input. Values from
1 to 99 can be set. The default timing is 5 seconds.
Example:
To set the activation time to 10 seconds, enter in sequence:
0 E start procedure
12345 E supercode
6 E Remote Key timing function
10 E relay activation time
9) Actuator function
One of the relays of 3348B can be used on the generic actuator command origi-
nating from the Simplebus Bus. Special programming is required on the external
unit as described in the TMs for Art. 4680, 4680C, 4681 and for 1621, 1622.
Programming the actuator function:
1) Enter "0" and "E" (start programming procedure code)
2) Check that the LED has lit up
3) Enter the supercode (see point 1), then "E"
4) Enter the number "7" ("actuator" function) followed by "E".
5) Enter the number of the relay to be associated with the command (1-2) fol-
lowed by "E".
6) Enter a number from 1 to 99 to indicate the monostable mode seconds
value, or enter "0" if you want bistable mode, followed by "E".
7) The LED should now turn off
Cancelling the actuator function:
1) Enter "0" and "E" (start programming procedure code)
2) Check that the LED has lit up
3) Enter the supercode (see point 1), then "E"
4) Enter the number "7" ("actuator" function) followed by "E".
5) Enter "0" and "E"
7) The LED should now turn off
Example:
Programming the actuator function:
0 E start procedure
12345 E supercode
7 E actuator function
1 E relay number
10 E relay closure time
ENABLING THE "KEY" BUTTON
Short-circuiting terminals CK and -, for example via a timer, makes it possible
to activate relay 1 without entering the relay code but by simply pressing the
"key" button .
REMOTE KEY INPUT (RK)
Closing this contact with ground activates relay 1 for the set time (see point 8).
The contact can be connected remotely up to 20 m max.
